Tutorials

The tutorials below are available for anyone to view; take a look and see how easy it is to use Mermaid. More tutorials are being developed; we’re presently working on explaining the more advanced features of Mermaid, so come back and you will find more as time goes on.

If you are an active user of Mermaid, the supporting materials (setup files, example metocean data) are available through the support portal. Simply search for the tutorial number, e.g. “Tutorial 3”, and the relevant material will appear.

Please note that as Mermaid is undergoing continuous development, there may be small changes in appearance from the recorded videos as time goes on. If this causes you any confusion, please get in touch via the support portal and we will help you out.
